Common Safety Indicators (CSIs)
CSIs provide harmonised data on accidents, precursors, and technical failures, enabling ERA to assess safety performance and support evidence-based policy decisions.
The European Union has established Common Safety Indicators (CSIs) under the Annex I of the Rail Safety Directive (EU) 2016/798 to ensure consistent and transparent monitoring of railway safety across Member States. CSIs provide harmonised data on accidents, precursors, and technical failures, enabling the European Union Agency for Railways (ERA) to assess safety performance and support evidence-based policy decisions.

The below brief guide outlines the arrangements the Agency has put in place to facilitate the reporting of CSIs data by NSAs, following the ERAIL disconnection.
